Repairing a Radar Truck in Call of Duty: Modern Warfare 4 DMZ can take longer than expected, especially when you have collected several vehicle components but cannot find the final Battery or Spark Plug. If you are working on the Mechanic Order, fixing the truck is only the beginning. You must also eliminate 19 enemies detected by its radar.
Fortunately, you do not have to find every component beside the same vehicle. Gas Stations and garages contain repair materials, components can be recovered from incomplete repairs when available, and spare parts can be carried into another deployment.
This guide covers all four Radar Truck repair parts, where to find them, how to fix a truck with missing components, and how to complete the Mechanic Order's 19 radar-pinged kills.

Quick Answer: How to Repair a Radar Truck in MW4 DMZ
To repair a Radar Truck in MW4 DMZ:
- Open the tactical map and locate a damaged Radar Truck.
- Approach the front of the vehicle and inspect its missing components.
- Collect the required Car Battery, Alternator, Spark Plug, or Vehicle Water Pump.
- Search Gas Stations and garages for parts, or recover usable components from another incomplete repair.
- Return to the truck and install the missing components to finish the repair.
For the Mechanic Order, you must then use the repaired truck's radar to detect enemies and eliminate 19 radar-pinged targets.
Missing the last component? Do not abandon your collected parts immediately. You may be able to recover components from an unfinished repair and use them toward another Radar Truck.
What Does the Mechanic Order Require?
The Mechanic Order contains two objectives:
- Repair a Radar Truck.
- Kill 19 enemies pinged by a Radar Truck.
The Order appears on Page 15 in one progression sequence, although your page number may differ.
The first objective requires restoring a damaged Radar Truck using vehicle repair components. The second requires eliminating enemies detected by the repaired truck's reconnaissance system.
Repairing the vehicle does not complete the entire Mechanic Order. You must also finish the 19-kill requirement.
Radar Truck repairs can also appear as separate activities during a deployment. Completing one of those repairs can finish the immediate side objective without completing the Mechanic Order's additional kill requirement.
Where to Find Radar Trucks on the Map
Radar Trucks are marked on the tactical map. Their positions can vary between deployments, so check your current map instead of relying on one fixed location.
To find a damaged Radar Truck:
- Open the tactical map after entering DMZ.
- Look for the Radar Truck markers.
- Choose a vehicle near a Gas Station or garage when possible.
- Travel to the marked location.
- Approach the front of the truck and inspect its repair requirements.
You may encounter several damaged Radar Trucks during a deployment. A voice announcement can also alert you when approaching one.
Should you choose a truck near a Gas Station?
Yes, when you have a choice.
Gas Stations and nearby garages are useful places to search for repair materials. Choosing a truck near one can reduce the distance you need to travel between the vehicle and potential component locations.
However, not every Radar Truck spawns beside a Gas Station. You may find damaged vehicles near other structures as well.
If you are completing other vehicle-related objectives during the same deployment, our MW4 DMZ Capture SAM Site guide explains how to secure SAM Sites and troubleshoot objectives that appear stuck.
All Four Radar Truck Repair Parts
Radar Trucks use four types of repair components:
| # | Repair Component |
|---|---|
| 1 | Car Battery |
| 2 | Alternator |
| 3 | Spark Plug |
| 4 | Vehicle Water Pump |
You do not necessarily need to collect all four from scratch.
When you interact with a damaged Radar Truck, its repair interface shows the required components. Some slots may already be filled, leaving only one or two missing items.
For example, a truck might already have an Alternator and Water Pump installed. In that situation, focus on obtaining the missing components rather than collecting unnecessary duplicates.
Best approach: Inspect the truck before beginning a long search. Knowing exactly what it needs can save valuable deployment time.
Where to Find Batteries, Spark Plugs and Other Parts
Gas Stations and garages are the best places to begin searching for Radar Truck components.
Look along shelves and inside accessible storage areas. Repair materials can appear as individual loot items that you can collect and carry to a damaged vehicle.
Search Gas Stations first
Gas Stations can contain Car Batteries, Alternators, Vehicle Water Pumps, and Spark Plugs.
However, one Gas Station may not contain every component.
For example, you might find a Water Pump and Battery in one building, while another location contains Alternators. If the Spark Plug is still missing, you may need to search additional stations.
Do not assume that a component has a guaranteed spawn at a particular Gas Station.
Check garages and shelves
Garages near damaged vehicles are another useful source of repair materials.
Check shelves carefully rather than searching only the entrance. Components may be placed in different parts of the building.
If you find one repair item, inspect the surrounding shelves before leaving.
Do you need to search every Gas Station?
No. Start by checking what the truck actually needs.
If you already have three of the four components, focus on finding the missing item. You can also consider switching to another Radar Truck if its repair requirements are easier to complete.
How to Repair a Radar Truck
Once you have the necessary components, return to a damaged Radar Truck and complete the repair.
Step 1: Find the repair interaction
Approach the front of the vehicle and interact with its repair point.
The interface displays the components needed to restore the truck.
Check which slots are already filled and which remain empty.
Step 2: Install the missing components
Supply the required items from your inventory through the repair interface.
The component slots can fill using the materials you have collected.
If you do not have everything required, the repair remains incomplete until the missing parts are supplied.
Step 3: Complete the repair
Once every required component is installed, finish repairing the vehicle.
The Radar Truck becomes usable, and its reconnaissance system can detect nearby enemies while the vehicle is driven.
If you were completing a repair side objective, check whether that objective has registered.
If you are completing the Mechanic Order, continue to the 19 radar-pinged kills.
Radar Truck Missing Battery or Spark Plug? Try This
A missing Battery or Spark Plug can prevent you from completing an otherwise nearly finished repair.
Instead of abandoning the objective, follow this checklist:
- ☐ Return to the repair interface and confirm the missing component.
- ☐ Search the nearest Gas Station or garage.
- ☐ If the item is unavailable, check another location.
- ☐ Inspect another damaged Radar Truck for useful components.
- ☐ Check whether an incomplete repair allows you to recover supplied parts.
- ☐ Use the recovered components toward a repair you can finish.
This approach is particularly useful when you have several repair materials but cannot find the final item.
If you still cannot complete a repair before the deployment ends, consider extracting with the components you have collected and preparing for another attempt.
How to Transfer Parts Between Radar Trucks
You can sometimes save time by transferring components from one incomplete Radar Truck repair to another.
If a vehicle cannot be fully repaired, check whether its repair interface allows you to recover the components already supplied. You can carry recovered parts to another damaged Radar Truck and use them toward a different repair.
Example: Moving parts to another truck
Suppose you encounter the following situation:
- Truck A is missing a Car Battery.
- You find an Alternator and Water Pump nearby, but no Battery.
- Truck B has a different combination of missing components.
- You recover usable parts from the incomplete repair at Truck A.
- You carry those parts to Truck B and complete its repair if you have everything required.
This can be more efficient than continuing to search for one missing component at the original location.
When should you switch Radar Trucks?
Consider switching when you have searched the nearby buildings, the required component remains unavailable, and another damaged truck offers a better opportunity to finish the repair.
Important: Check the available repair interactions before moving components. Do not assume every installed part can always be removed or that every damaged truck will contain useful spare materials.
Can You Extract with Radar Truck Repair Parts?
Yes. You can extract with collected Radar Truck repair components and bring them into a later deployment.
This is useful if you find a Battery, Spark Plug, Alternator, or Water Pump while completing another objective.
Rather than selling or discarding every spare component, consider keeping useful repair materials in your stash when you have enough space.
Best way to prepare for another deployment
If you plan to complete the Mechanic Order later:
- Keep the repair components you have successfully extracted.
- Check your available inventory and stash space.
- Bring the required materials into your next deployment.
- Locate a damaged Radar Truck on the tactical map.
- Inspect its missing components and complete the repair.
Bringing parts with you can reduce the time spent searching Gas Stations and leave more time for the 19-kill objective.

How to Get 19 Radar-Pinged Kills for the Mechanic Order
After repairing a Radar Truck, you must eliminate 19 enemies pinged by its radar.
The important distinction is that the enemy must be detected by the truck's reconnaissance system. Do not assume that every ordinary kill will count.
Step 1: Drive the repaired Radar Truck
Enter the repaired vehicle and begin driving.
The truck's radar can ping nearby enemies as you travel through an area.
Step 2: Move toward enemy activity
Find an area with hostile targets and use the Radar Truck to detect them.
Try to avoid clearing every nearby enemy before repairing the vehicle. Keeping enemies available gives you targets for the second objective.
You can move between enemy-populated areas as needed.
Step 3: Kill an enemy detected by the radar
Wait until the Radar Truck pings an enemy, then eliminate that target.
After your first radar-pinged kill, check the Mechanic Order counter.
Look for 1/19 progress. If the counter increases, you have confirmed that your approach is working.
If it does not increase, check that the enemy was detected by the repaired truck's radar before attempting another kill.
Step 4: Continue until you reach 19/19
Repeat the process with additional radar-pinged enemies.
If nearby buildings have been cleared, drive to another area containing hostile targets.
You do not need to find all 19 enemies in one location.
Once the Order counter reaches 19/19, the radar-ping kill requirement is complete.
Best strategy for finishing the 19 kills
The most efficient approach is to prepare repair materials before deployment whenever possible.
This allows you to repair the truck earlier and spend more time finding enemies.
Avoid unnecessary fights while searching for components, and confirm that your first detected kill counts before continuing.
If you are also completing reconnaissance-related objectives, our MW4 DMZ Eyes Everywhere Recon Drone guide explains another mission that requires marking enemies rather than simply eliminating them.
Mechanic Order Not Progressing? What to Check
If your Mechanic Order counter is not increasing, identify which objective is incomplete.
Radar Truck repair is not counting
Check that every required component slot is filled and the repair has actually completed.
A partially repaired vehicle does not satisfy the completed-repair requirement.
If the interface still shows a missing item, collect that component before trying again.
Radar-ping kills are not counting
Make sure the truck's radar has detected the target before eliminating it.
If a kill does not register:
- Check that the vehicle repair is complete.
- Move the truck toward another enemy-populated area.
- Wait for the radar to ping a target.
- Eliminate the detected enemy.
- Check the Mechanic Order counter again.
These steps help you verify the required detection condition. They are not a guaranteed fix for every possible progression issue.
You repaired the truck but the Order remains incomplete
Check whether you have finished the 19-kill requirement.
The repair objective and radar-ping kill objective are separate. Completing one does not automatically finish the other.
You are running out of deployment time
If you have collected valuable components but cannot finish the repair, consider extracting with them.
You can bring retained components into another deployment and attempt the objective with more time available.
Frequently Asked Questions
How many parts are needed to repair a Radar Truck in MW4 DMZ?
Radar Trucks use four component types: Car Battery, Alternator, Spark Plug, and Vehicle Water Pump. Some slots may already be filled, so inspect the truck to determine which components are missing.
Where can I find Radar Truck repair parts?
Search Gas Stations and garages, especially shelves and storage areas. Different locations may contain different components, and one building may not provide everything required.
What if I cannot find a Car Battery or Spark Plug?
Search another Gas Station or garage. You can also inspect other damaged Radar Trucks and check whether useful components can be recovered from an incomplete repair.
Can you transfer repair parts between Radar Trucks?
Yes. When the repair interaction permits recovery, you can take components from an incomplete repair and use them toward another damaged Radar Truck.
Can you extract with Radar Truck repair components?
Yes. Collected repair components can be extracted and brought into a later deployment, provided you retain them in your inventory.
How do you get 19 radar-pinged kills?
Repair a Radar Truck, drive it to detect nearby enemies, and eliminate targets after they have been pinged. Check your Mechanic Order counter and continue until it reaches 19/19.
Does repairing a Radar Truck complete the Mechanic Order?
No. The Mechanic Order also requires 19 kills against enemies pinged by a Radar Truck. Both objectives must be completed.
Final Tips: Best Way to Complete the Mechanic Order
If you already have repair components in your stash, bring them into your next deployment and choose a Radar Truck near a Gas Station when possible.
Inspect the missing components, complete the repair, and preserve nearby enemies for the 19 radar-pinged kills. Confirm that your first detected kill registers before continuing.
If you cannot finish the repair, recover usable components where the interface allows it and consider extracting with your remaining parts for another attempt.
The key is to prepare your repair materials early, finish the truck, and leave enough deployment time to complete all 19 radar-pinged kills.
